To all whom it may concern.-

Be it known that I, HARVEY H. BLACK- MAN, a citizen of the United States, residing at Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Mirror Attachments for Brooders, of which the followin is a specification.

his invention relates to new and useful improvements in brooders, and more particularly to a mirror attachment for the lamp thereof, whereby the condition of the light may be readily ascertained.

In the construction of brooders wherein a lamp is .employed for generating heat the supporting-frame which extends to the front wall of the brooder is provided with an opening or peep-hole which is closed by a sheet of mica. This opening is for the purpose of enabling one to look into the interior of the brooder and ascertain the condition of the light. Inasmuch as the lamp is positioned in the lower portion of the brooder, when it is desired to look through the peep-hole it is necessary for a person to get on his knees or to stoop low. This is a tiresome and oftentimes inconvenient method, especially when the brooder is set in a lot of wet grass. should be here stated that the brooders ordinarily employed are of varying types, some of which possess the special construction of lamp and lamp-frame outlined above.

My invention, therefore, aims to dispense with the necessity of assuming astoopingposture in looking through the opening, and to this end it embodies a mirror mounted in a suitable frame which is setat a proper angle to the peep-hole, so that one can obtain reflection of the light from the mirror and ascertain perfectly the conditions within the brooder while standing in an upright or nearly upright position.

The detailed construction will appearin the course of the following description, in which reference is had to the accompanying drawings, forming a part of this specification, like characters designating like parts throughout the several views, in which Figure 1 is a side elevation of the brooder of that type of construction in which the lamp carries a specially-constructed frame, showing the relative arrangement of the various parts and suggesting diagrammatically the arran ement of the lamp and the position of the mirror with relation to the lampsupport. Fig. 2 is a perspective view of the lamp and the elements relating thereto. Fig. 3 is a fragmentary longitudinal section showing the arrangement of the mirror upon the lampframe.

In the practical embodiment of my invention in the construction shown in Figs. 1, 2, and 3, A designates a brooder of conventional form which is formed with a lower por tion 1 to receive the lamp and lower part of the heating-chamber, a floor 2 above said lower portion, which is indicated by dotted lines in Fig. 1, a hover 3, and an inclosing screen 4, supported upon suitable framework 5. A lamp 6 is positioned in the lower portion 1 of the brooder and embodies an oilreceptacle 7, upon which is mounted an L- shaped frame 8, formed with a vertically-extending leg 9, which is designed to close a corresponding opening in the front Wall of the portion 1 of the brooder. A burner 10 is carried by the receptacle 7 above the frame 8. The burner 10 is regulated from the exterior by a link 11, passing through the leg 9 and terminatin in a knob or handle 12, the link 11 being suitably connected to the operatin shaft 13 for raising and lowering the wic The leg 9 of the frame 8 is formed with an opening which is closed by a sheet of mica 14. and serves as a peep-hole for the interior of thebrooder. the mica peep-hole 14 is a mirror 15, which is mounted in a frame 16, provided at its lower edge with an angular flange 17, by which the frame is secured to the leg 9. For the pur' pose of withdrawing the frame 8 and the lamp 6 afinger-loop 18 is secured to the leg 9, preferably adjacent to the base thereof.

The mirror 15 is preferably arranged at an angle of forty-five degrees with respect to the mica peep-hole 14, so that the reflection from the interior will strike said mirror at an an le of one hundred and thirty-five degrees. This is clearly shown in Fig. 3, where the course of the reflex rays is indicated in dotted lines and lies at a right angle to the course of the incident ray.

The frame 8, the mirror-frame 16, and the oil-receptacle 7 are preferably constructed of metal, though this is a minor feature, and any material well known in the art may be em- Positioned directly in front of ployed in accordance with its adaptability for the varying conditions and places in which the brooder is employed.

Having fully described my invention, what I claim is 1. The combination with a brooder-lamp, and the frame carried thereby, said frame being formed with a vertically-extending portion having a peep-hole therein, of a mirror secured to said vertically-extending portion adjacent to said peep-hole.

2. The combination with a brooder-lamp I and the frame carried thereby, said frame being formed. with a vertically-extending portion having a peep-hole therein, of a mirror positioned in front of said peep-hole and disposed to lie at an angle to the plane thereof.

3. The combination with a brooder-lamp, and the frame carried thereby, said frame being formed with a verticallyextending portion having a peep-hole therein, of a frame secured to said vertically-extending portion and disposed to lie at an angle thereto in front of said peep-hole and a mirror mounted in said frame.

4. The combination with a brooder-lamp and the frame carried thereby, said frame being formed with a vertically-extending portion having a peep-hole therein, of a mirror positloned at an angle to said peep-hole.

5. The combination with a brooder-lamp, and the frame thereof, said frame being formed with a vertically-extending portion having a peep-hole therein, and a sheet of mica inclosing said peep-hole, of aframe secured to said vertically-extending portion and disposed at an angle thereto in front of said peep-hole, and I a mirror carried by said frame.

6. In combination with a brooder-lamp, and the frame thereof,said frame being formed with an singularly-extending portion having a peep-hole therein, and a sheet of mica inclosing said peep-hole, of a frame rigidly secured along its entire base edge to said angularlyextending portion and disposed at an angle thereto in front of said peep-hole, and a mirror carried by said frame.

In testimony whereof I afliX my signature in presence of two witnesses.

HARVEY H. BLAOKMAN.
